Fig. 34 is a fragmentary view in section through the mechanism employed for adjusting the tracks upon which the crossed strands of the fabric and the embracing staples are carried from the crimping disks to the tying disks, as though taken on line 34-34 of Fig. 35. Fig. 35 is a transverse section through one of said tracks and adjusting mechanism, as on line 35-35 of Fig. 34. Fig. 36 is an enlarged sectional view through a plurality of 'he tying disks longitudinally ofthe shaft adapted as hereinafter explained to trans- .carries a gear 7 and fa pinion 8 whichvare mit movement to tlie various operative parts of the machine. y

The longitudinal or strand Wires 9, excepting the selvage wires, are fed into the machine over a series of grooved disks 10 which are disposed in parallelism upon a transverse shaft 11 such distance apart as will afford the desired spacing between the strand or longitudinal wires of the fencing, there 'being one of said disks 10 for each of said strand wires, and said disks being keyed to the shaft 11 byrmeans of the keys 12, as shown in Fig. 12, in a manner to enable them .to be adjusted longitudinally thereof to vary the spacing between the strand wires as may be desired.l Coperating with the disks 10 and runnin in peripheral contact therewith are the dis rs 13. The disks13 are secured to the parallel shaft 14 by means of keys 15 in the same manner and'for the same purpose that Athe disks 10 are secured to the shaft 11.

4The disks 13 are alsochanneled and are so disposed as to coperate in pairs with the disks 10, the arrangement being suchthat each pair of said disks receives one of the strand Wires between their peripheries which pass around the lower arc of the disks 10 in their travel through the machine as the disks 10 and 13 are revolved in unison in opposite directions. .i j v The transverseor stay wires 16 are fed to the machine upon an inclined table F17 beneath a guide 18; which directs then into position transversely of the disks 1() adjacent the peripheries thereof. To provide for picking the stay wires successively from the` inclined table .17 and to space them the proper distance apart as they are carried into the machinethe disks 10 are provided at their peripherieswith a plurality of spaced plates 19 secured by the screws 20 to the die blocks 21 set in the peripheries of said disks, said plates each havin a curved finger or hook 22 which extends yond the perlphery of the disk and is adapted to engage the lowermost stay Wire on the table 17 and carryl said stay` wire forward as the disk 10 revolves so as to present it under the strand wires which feed onto the disks 10 after the picking of the stay wires'from` the table 17 by the fingers of the plates 19, the intervals between the operations of picking the suc.- cessive transverse wires from the table demaintaining "the crossed trandsoffthelfabricfin proper relative po- :su ccompiishedgby means of coperating dies and-.23 pivhichsare" set in the peripheries of (i and?` lrespectively, and, which yrovidedfin their faces Withchannels 24 %"crossing` at" rightangles,` there being "unctureof said Vchannels adeeper deprei b Q16 i "Thealrangementof "partsisvsnch that henthest`ay` Wires arepicked `from the table i heywillvlief" in `the transrerse` channels Billie die'blocks 2l lwhile the strand Wires will in fthefchannelsQ 1ofz the die blocks t Q1 ssthestay wires kThis position is mainuntil th efdisks enipheralcont t atfwhichtime the die crossed s lands infthe channel the correspondiiig relat'io with nels infthe d npolr the "crossed strands as the dies together` `rait 1 said "strands between i.)

die blrck into a socket 51 in the disk 43 in which the head of said bolt lies. YEmbracing. each of said bolts betwelenethl'bafse of the recess 49 and the die 45 is a coiled spring 52 which normally `holds the die v45 projecting, as shown in Fig. 19, but which will to permi cess 49, as shown in Fig. 20,` for purposes through the tying dies are first caused to hereinafter stated. As the rotation of the tying disks draws the crossed strands thereencounterthe staples or ties, in Fig'. 31. y

The operation of tying the staples about or upon the crossed strands 'to j oin them firmly 'together at their junctures will be described with reference to one pair of dies only, with the understanding that fthe same operation' takes faces ofthe other sets of dies and that with respect to all ofthe corresponding sets of dies in the series of tying disks thel operation is simultaneous. As the tying dies close -together upon the crossed strands and the as illustrated embracing staple, the loop of the staple enters the transverse concavity 53 inthe Vmale die 44 whereby the angular portions 54 of the legs of the staple which embrace the stay wire are crowded into .the parallel l longitudinal depressions 55 and 56 respectively, as more clearly shown in Figs. 2414.

and 25. Atthe same time the terminal of the longer leg 59 of the staple enters the transverse concavity 60 inthe malleldiegand the terminal of the shorter leg 6l of the v staple enters the transverse concavity 62 in said male die. The shape of the transverse concavity 60 and 62 is such that as the dies move together the terminals of the legs of the -staple are bent across the strand wire from opposite sides in a curved p lane,

as clearly shown in Figs; 28 and 29. "The .crimp in the strand wire where it crosses" the stay wire enters the depression 57 .in the common to each set of the tying- 48 and,l

t the die to recede into the replace between the working i male die, and the straight portions of the stay wire enter the transverse channel 58v crossing said die as the working faces of the dies come more closely together. As pressure is brought to bear upon the female die it gradually recedes against the action of -its spring 52, allowing said die to enter the recess49 in the die block, said die ulti mately seating on the bottom of said recess at the completion of the tying operation, as clearly shown i tion theYtying of the knot is completed. The rotation of the tyin disks repeats said operation as the pairs o tying dies are successively brought together atA the meetingl points between their peripheries, which o /eration' it will be understood is concurrent y 1 disks act# ing upon one of the stay wires o the fabric. As the female dies recede intoi=the recess 49 in their dier blocks during the, operation of tying, the longitudinal'strands') enter and lie in the channels 63 in said blocks (see Fig. 24) and the cross strands or stay' wires enter and`- lie in the transverse channels 64 in said die blocks, leaving the staple' lane of the 7 outer face ofthe blocks 4 8, asc early shown' and crossed strands below the in- Fig. 21, in which `tion the tyin staples remain fast in 'thdxiles whereby the?7 are temporarily 'lockedv to the 1peripheries of the disks 43 so that'through t e rotation of said disks the strand wires are drawn upon to pull them througlh4 the machine and carry forward the comp eted fabric.

Rotation is imparted to the tying disks through the medium of thegear 7 on shaft 6,;which meshes with a large gear wheel 65 on'v the shaft 66 carrying the series of lower tying disks 43. Also mounted on the shaft 66 is a large .beveled lgear wheel'67. On the shaft 68 of the upper series of tying disks'is a large beveled gear 69, and fast to a vertical shaft supported at its ends in boxes carried on the vouter ends of the shafts 66 and 68,are the beveled inions l71 and 72;'y the pinion 71` meshing w1th the gear wheel 67, and the pinion V72 meshing with the gear wheel 69. By this arrangement the shafts carrying the tying-'disks yare caused to revolve in unison in opposite ,directions at the sameI rate of speed.

v, The fabric passes from the peripheries of the lower tying disks ,43 between the crimping rolls 73 and 74,v said rolls com prising hollow bars or tubes 75 extending` between and secured in the ends thereof, and which are so positioned as to mesh together and crimp the fabric as saidy rolls roll together in a manner clearly illustrated in Fig. 5. This transverse crimping of the fabric is designed to give elasticity thereto so .that when strained longitudinally when hung it will remain under such tension as to keep it taut.

Mesh- Ling with the beveled gear 90 upon the spin-` dle ofeach ot the twisters is a beveled gearv ,100; mounted .upon a vertically disposed chine, whereby asysaid shaft revolves the desired rotary'movement is imparted to the spindleS. This method of rotating the -spindle isleinployed at one side of the machine.` To providelfor rotating the spindle of the opposite side of the'machine in the opposite directioman idle gear 107 (see Fig. is interposed between the gear 106 on thedriving shaftand the gear 1.05 on the. shaft 104whereby thedirection of rotation of the spindle 85 driventherefrom will be reversed,` y

` I.As the travel of the longitudinal strands through the machine is continuous it is necessary to provide for actuating the twisters-seas to enable them to follow the move` nient of the selvage strands during 4the oper# ation of twisting `the terminals of the stay wires thereto. `To accomplish this result a reciprocal movement is imparted toeach of the twister heads through the mediumlof yay lever t8fulcru`med at 109 to a portion of engaged by a eamilll mounted on the main shaft 2 to rotate therewith,` and through upon ,its fulcrum. `Atthe upper end ot pin 113 projectingfroma collar 1111, which thelever is a` slot 112 `adapted to receive a.

As the lever 8 recprocates, the spindle 85 will be caused toj slide longitudinally forth "and backl through the beveled pinion `90 and the em- The cam 111` is so positioned upon the shaft 2 that whent the parts in the operation of the machine reach the position shown in Fig. G'the lever 108 g tudinally` through its' supporting bearing i will be actuatedto 'slide the spindle longi serving as a .threaded in a jects over the marginal strand 84. After encountering the projecting end of the stay wire the forward travel of the twister head by the graduation of the cam 111 is made to equal the speed at which the strand wires are moving through the machine so that during the operation of twisting the terminalsof the stay wire around the marginal strand wires the twisters travel with the fabric, the' position of the parts'at the completion of the twisting operation being illustrated in Fig. 7, at which time the high point of the cam 111 passes from engagement with the roller 110 of the lever 108 when the retractor spring 115 will return said lever arm, the twister-head, and the spindle to the initial position shown in Fig. 6 where they remain until 'the succeeding strandwire is brought into position to have the terminals thereof wrapped around the selvage wires, when theoperation just described is repeated.

In order to adapt the machine for making fencing of different widths it is necessary to vary the distance between the selvage strand wires. plished it is necessary to so mount the twisting device at the sides of the m'achine as to render them adjustable toward and from eachother. For this purpose therefore the brackets 88 carrying the twisting mechanism are each mounted to adjust'transversely upon a fixed slideway 116 on the main frame, shown more clearly in Figs. 6, 7and 32. Movement is imparted to said brackets' to adjust them laterally by means of the 'upper and lower screw shafts 117 and 118 respectively, having threads on the opposite ends thereof. The upper shaft is s nut 119 carried in .the left hand bracket (see Fig. 32), the smooth por- 'tion of saidshaft serving as a yslide for the right hand bracket, theterminals of said screw shaft being journaled in the sides of the frame. The lower screw shalft 118 is threaded in a nut 120 on the .right hand bracket, the smooth portion of saidlshaft slide foi` the left hand bracket, the terminals of said shaft 118 being. also journaled in the sides of the frame. The outer ends of said screw shafts are squared to receive the cranks 121 through the medium of which the screws may be turned to `slide the brackets 88 with the twisting mechanism thereon transversely of the machine, so as to bringthe salvage wires closer together or farther apart as may be desired. To enable the twisting 4mechanism to be drivenat anv point of 'adjustment the driving gear-,106 is made to adjust along the shaft 2 through the medium of a key 122 carried thereby adapted to slide in a way in said shaft.

In order to adapt the machine for the manufacture of fencing wherein the strand are common to all of l at 127, the projecting To enable this to be accom- To enable the squared ends 128 wires .may be placed any desired distance apart itis necessary that the crimping disks, the tracks over which the 'strands pass, and

of the lmachinein opposite directo their respecthe shafts by means of the longitudinally extending keys 123, `'which the diskson each shaft whereby the disksare caused to turn with their shafts but may beY moved longitudinally thereon.' vIn order to hold the tying diskson each shaft `in alined coperation and at the same time permit of an adjustment of said disks longitudinally. of `their shafts concertedly or individually an adjusting screw 124 (see Fig. '36) 4is employed which passes through and is threaded in a nut 125-in each of said disks between th/ose at the ends of the shaft. In the end disks 126 the screws .124 are journaled, as shown ends of which screws `the-tying disks be made adjustable trans y y versely tions. The tying disks 42 and '-13 are splined are squared as shown'y at 128 forthe applicai tion ofa. wrench.l The nuts 12.5 in which the adjusting shafts are threaded are nor- 'mally loose within the disks and are held from rotation by thejset screws 129 which pass through the peripheries of the disks into engagement withsaid nuts, the heads. of said screws lying in sockets 130 in the peripheries of said disks, whereby the screws are rendered accessible for manipulation and yet are so disposed as not to in-l terfere with the feeding of the strands onto and off of said disks-as they revolve. When the nuts 1 25 in the disks are not locked by the set screws 129 the rotation of adjusting screw 124 will cause said nuts to rotate withinthe disks and will not adjust the disks along their supporting shaft. WVhen it is desired to shift one or more of the disks the set screw 129`is turned so as'to hold from rotation the nut of the disk which it his desired to adjust when by turning the adjusting screw the said nut will be caused and shift the shaft in either direction accordingly as the screw 124 is rotated; The end disks 126 are rigidly locked to the shaft at all times by means of set screws 131 so as to afford an anchorage for the screw 121. This arrangement alines all of the disks upon the shaft and causes themvto turn in unison therewith.

of the ad- 'usting screws to be reached from the outside of the machine for the purpose of adjusting the tying disks, the driving gears' 67 and .69 (see Fig. 1) are provided with. apertures 132 through which a wrench may be passed for the purpose of manipulatingthe adjusting screws 124. The adjustment of the tying 'disks along` their shafts makes necessary a corresponding adjustment of the tracks 29, which diframe,
